With the current policy neither of them is listed, so listing A would be an improvement. The goal is to keep things simple, and listing only the largest contributor looks like the simplest solution. For example, listing the two largest contributors would lead to similar problems. What should we do if A and B each write 34% and C writes 32%? In a previous version of the draft, we had required a full list of copyright holders to be listed somewhere in the file, and 60% of the lines to be accounted for: We changed that because neither tracing the number of lines nor maintaining a list of authors in every ebuild seems feasible.

That would get us into a discussion on which portions of an ebuild are copyrightable and which are not. Again, we want simple rules there.

See above. Explicitly listing only one copyright holder in the copyright line looks like the simplest possible solution. Listing nobody would be even simpler, but I think that you cannot have a copyright line without at least one entity. Also note that the exercise is _not_ about giving credit to authors (and we currently don't do that with the Foundation copyright either). The purpose of the copyright notice is to make a statement that the work is copyrighted, in order to defeat a possible defense of "innocent infringement". Ulrich
